JPH0437429A - Manufacture of tube material for making ornament such as body ornament, head ornament - Google Patents

Abstract

PURPOSE:To obtain novel tube material effective to a decoration by obtaining a round stock in which the outer circumferential surface of an inner material made of tubular material is coated with an outer material from the different material, squeezing the round stock to obtain a flat stock, grinding its surface, thereafter, rounding the flat stock in the shape of a tube. CONSTITUTION:The tubular inner material 1 made of gold is inserted into the inner diameter hole of the tubular outer material 2 made of platinum and then a round stock 3 is obtained by drawing the resultant material. Then, the round stock 3 is squeezed to obtain a flat stock 4. Thereafter, the upper surface of the flat stock 4 is ground to expose a part 5 of the inner material 1. Then, the flat stock 4 is rounded in tubular shape as this inner material surface is exposed on the outer circumferential surface, consequently, a spirally twisted tube stock 6 is obtained. Sometimes, silver, platinum, iridium, etc., are used as the inner material 1 and gold, silver, iridium, etc., are used as the outer material.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing pipe materials for manufacturing personal accessories such as chains, necklaces, and head accessories such as hair clips.

[Conventional technology]

BACKGROUND ART Conventionally, pipe materials of this type having an uneven pattern such as serrations on the surface are known.

[Problem to be solved by the invention]

Personal accessories and other accessories manufactured using the pipe material described in the prior art lack uniqueness and novelty, and tend to fall into a rut.

It is an object of the present invention to provide a new method for manufacturing a pipe material that is effective for use in the manufacture of decorations and breaks the aforementioned tendency toward rut.

[Means to solve the problem]

In order to achieve the above object, the method of manufacturing a sound material for manufacturing shaft tools for personal accessories, head accessories, etc. of the present invention is as follows. A step of obtaining a round material (3) covered with an outer material (2) made of a different material, a step of obtaining a flat material (4) by subjecting the round material (3) to a pressing process, and 2 of the flat material (4). A step of grinding the front surface to expose a part (5)r of the inner material (1) to the outside, and a step of exposing the flat material (4) to the outside after the grinding, and the exposed inner material is located on the outer peripheral surface. This process involves a process of shaping the material into a pipe shape.

〔Example〕

To explain the embodiments of the present invention with reference to the drawings, first, a pipe-shaped inner material made of gold (1), a pipe-shaped outer material made of all platinum (2)
A round material (3
).

Next, the round material (3) is crushed to form a flat material (4).
).

Thereafter, the front surface of the flat material (4) is ground to expose a portion (5) of the inner material (1) on the same surface.

Next, the flat material (4) is rolled into a pipe shape with the inner material exposed surface located on the outer circumferential surface, thereby forming a spirally rolled pipe material (
6).

In the present invention, the inner material (1) is made of silver, platinum, iridium, etc.
The outer material (2) may be made of gold, silver, iridium, etc., and the inner material (1) may be made of gold wire. 71') is cut off and then rolled into a pipe shape, and the abutting parts (8) on both sides of the flat material (4) rolled into a pipe shape are secured by brazing, plasma welding, etc. I may wear it.

[For production]

Personal accessories, head accessories, etc. made of the tube material obtained according to the present invention have a decorative function due to the exposed portion (5) of the inner material (1) and a decorative function due to the exposed portion of the outer material (2). Together they create originality and novelty.

The tube material obtained according to the present invention is stored in a spiral shape as shown in FIG. 4, and used by cutting it as needed.

〔Effect of the invention〕

Since the present invention has the above-described structure, it can be used to manufacture a new pipe material that is effective for manufacturing personal accessories, head accessories, etc., and has the effect of greatly contributing to breaking the tendency to become rutted. It is something that plays.

Claims (1)

[Claims] A step of obtaining a round material (3) in which an outer material (2) made of a material different from the abutting inner material (1) is attached to the outer peripheral surface of an inner material (1) made of a material such as wire or pipe; A step of applying a pressing process to obtain a flat material (4), and a step of applying a grinding process to the front surface of the flat material (4) to expose a part (5) of the inner material (1) to the outside. , a step of rolling up the flat material (4) after the grinding process into a pipe shape in which the inner material exposed surface is located on the outer circumferential surface. .
